AREA FORECAST DISCUSSION National Weather Service Wakefield VA 337 AM EST Fri Jan 24 2020

SYNOPSIS. High pressure continues to slide offshore today. Low pressure tracks across the region tonight into Saturday morning. High pressure builds in for the end of the weekend and into the first part of next week.

NEAR TERM /UNTIL 6 PM THIS EVENING/. As of 330 AM EST Friday .

This morning there is a surface high in New England which will slide off the coast as the day goes on. Meanwhile to our west, a closed upper low over the MS valley is slowly progressing eastward. At the surface there is one low pressure system over the TN valley and another system that will develop over the deep south and move northeast towards our region during the day today. KWAL 00Z sounding shows easterly flow near the surface with SW flow aloft. The low level easterly flow continues to bring in shallow moisture which is resulting in patchy areas of low stratus across the area. Patchy fog has also developed in some inland areas where clear skies earlier tonight allowed temps to quickly cool to the dew point. Low temps this morning will be in the lower 30s inland and lower 40s close to the coast.

Precip from the approaching low to our SW will get close to the area today, however most of the area should remain dry but cloudy through the afternoon. Best chance for light showers would be across western portions of the area. As the high moves off the NE coast today, our flow will eventually become more E/SE. Dew points will rise into the 40s and 50s by late in the day. High temps this afternoon will range from the lower 40s north to lower 50s southeast.

SHORT TERM /6 PM THIS EVENING THROUGH SUNDAY NIGHT/. As of 330 AM EST Friday .

The low pressure system will cross the area early Saturday. Pops begin to increase across the west around 00Z. Timing of the main line of convection based off latest guidance is around 03Z out west, 06-12Z for Richmond, South Central Virginia, and inland NE NC, and 12-18Z for the VA peninsula and MD/VA/NC coastal areas. While the rain will be heavy at times, the line will be moving quick enough that flooding should not be a concern, outside of nuisance poor drainage areas. Highest rainfall totals will be out to the west with totals decreasing as you head southeast. Expect 1-1.25 inches across the far west, 0.75-1.0 for Richmond up to the MD eastern shore, and 0.3-0.5 for NE NC and the Tidewater area. Can't rule out an isolated rumble of thunder as the line progresses across the area, however the convection is expected to be fairly shallow. Only place there is slight chance thunder in the grids is across the far SE.

The cold front associated with the low clears the area by late Saturday morning into the early afternoon. Despite the frontal passage, Saturday will remain warm with high temps ranging from the lower 50s NW to near 60 across the SE. High pressure will build in the remainder of the weekend. Temps will be a bit more seasonable on Sunday with low temps in the 30s and high temps in the upper 40s to lower 50s.

LONG TERM /MONDAY THROUGH THURSDAY/. As of 330 PM EST Thursday .

Dry/seasonable conditions prevail through at least Wednesday with west to northwest flow at the surface and aloft along w/ weak sfc high pressure to our N. Any Arctic air will be well to our north (across central/nrn Canada) through the extended period and potentially well beyond that. Highs will mainly range from the upper 40s-mid 50s from Mon-Wed, with morning lows in the low-mid 30s in most areas (except for some upper 30s across coastal SE VA/NE NC).

There is less agreement in the models as we head into the late week period. The 12z/23 GFS is forecasting high pressure to settle across the area by late Thu night, while upper troughing deepens over the central CONUS (w/ sfc low pressure developing along the wrn Gulf coast). The ECMWF/GEM are forecasting a weak shortwave trough to approach our area from the W during by Thursday timeframe as low pressure develops off the Carolina coast. The ECMWF/GEM solution would allow for rain chances to increase by Thu. For now, went with a blended solution w/ PoPs of 15-25% for the area from Thu AM-Thu night. Highs Thursday range from the mid 40s NW to the mid 50s SE. Lows Thu night mainly in the 30s.

AVIATION /09Z FRIDAY THROUGH TUESDAY/. As of 1230 AM EST Friday .

VFR to start the TAF period. A low level easterly flow is bringing pockets of MVFR cigs just west of RIC but for right now am leaving them VFR for at least the first few hours of the TAF period. Patchy fog is also possible early this morning as the temp falls near the dew point. Have tempo groups in for lowered visbys at SBY and PHF. Cigs at all locations except SBY will lower to MVFR this morning ahead a system that will impact the area later in the evening. Winds today will be easterly eventually becoming southeasterly 5-10 kts.

Low pressure will advance across the region late Friday through Saturday morning, bringing rain and degraded flight conditions. Conditions will improve Saturday afternoon, with a return to VFR conditions at all TAF locations through the remainder of the weekend.

MARINE. As of 315 AM EST Friday .

High pressure centered from the New England coast to Atlantic Canada today, bringing an E/NE flow to the local area, with winds gradually shifting more to the E/SE this aftn/evening and eventually to the S tonight/early Sat AM.

SCA headlines are in effect currently across the coastal waters S of Cape Charles Light (for elevated seas of 4-5 ft), with sub-SCA conditions prevailing elsewhere. However, as sfc low pressure W of the Appalachians moves ENE later today, and across the local waters overnight/early Sat, wind speeds will increase to 10-15 kts with gusts around 20 kts by late in the day today, and to 15-20 kts with gusts up to 25 kts for tonight into Sat morning ahead of the approaching low pressure system. Waves/seas build throughout the day with the persistent easterly flow, and by Sat morning expect 2-4 ft waves in the Bay and seas 5-8 ft.

Cold front associated with the low pressure system crosses the area waters Sat morning into early Sat aftn. Westerly flow expected after the frontal passage. At this time, have SCAs for all coastal waters by late this aftn, then spreading into the Bay, lower James, and Currituck Sound late this evening through Sat AM. Pressure rises are fairly minimal Sat aftn/Sat night/Sun as the sfc high builds in from the Gulf coast as low pressure lingers well off to our N. Not much in the way of any cold air advection either, so overall do not anticipate needing any headlines after Sat AM other than for lingering seas on the coastal waters due to swell and dominant periods of 9 sec or greater into Sun AM.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
